Designed for compact commercial installations where discreet appearance, intelligent event detection, and built-in audio recording are important, the DS-2CD2543G2-IS combines 4MP video, human and vehicle classification, Smart IR illumination, and local edge storage in a low-profile dome housing.
The camera captures video at up to 2688 × 1520 resolution and is available with 2 mm, 2.8 mm, and 4 mm fixed lens options. Human and vehicle target classification supports more relevant motion and perimeter events, helping security teams reduce alerts caused by general background movement.
Smart IR illumination provides nighttime visibility up to 30 meters, while 120 dB WDR, BLC, HLC, and 3D DNR help maintain usable image detail around entrances, corridors, parking structures, and other areas with challenging lighting conditions.
The DS-2CD2543G2-IS includes a built-in microphone, Audio I/O, alarm input and output, and a microSD card slot supporting up to 512 GB. H.265+ compression, IEEE 802.3af PoE, ONVIF Profile S/G support, IP67 weather protection, and an IK8-rated enclosure support flexible commercial deployment.
